Dia (also Jupiter LIII) is one of the smaller moons of the planet Jupiter .
discovery
Dia was discovered on December 5, 2000 by the astronomers Scott S. Sheppard , David C. Jewitt , Yanga R. Fernández and Eugene A. Magnier and was given the provisional designation S / 2000 J 11. The object was not able to return for a long time to be found and was therefore considered lost. The rediscovery of S / 2000 J 11 was only announced in September 2012. On March 7, 2015, the moon of Jupiter was officially named after Dia , who is a female equivalent of Zeus in Mycenaean mythology and the consort of Ixion in Greek mythology .
Orbit data
Dia orbits Jupiter at a mean distance of 12,174,000 km in 274 days and 10 hours. The orbit has an eccentricity of 0.21 and is inclined 28.3 ° from the local Laplace plane , which roughly coincides with the orbit plane of Jupiter.
Due to its orbital properties, Dia is assigned to the Himalia group , named after the Jupiter moon Himalia .
Physical data
Dia has a diameter of about 4 km. Their density is estimated at 2.6 g / cm³. It is presumably composed mainly of silicate rock and has a very dark surface with an albedo of 0.04, i.e. that is, only 4% of the incident sunlight is reflected. Their apparent brightness is 22.4 m .
